" AUTOMOBILE.

SPECIFICATION forming part of Letters Patent No. 780,798, dated January24,1905.

Application filed Augnst 22, 1904. Serial No. 221,721.

To a/ZZ whom t may concern.-

Be it known that We, AREA HOLMES and AL- BERT HOLMES, citizens of theUnited States,

.elsewhere where such joints may be desired;

and the invention consists in certain novel vertical longitudinalA'section thereof.

constructions and combinations of parts; as will be hereinafterdescribed and claimed.

In the drawings, Figure 1 is a perspective view of our invention as in:use. Fig. 2 is a Fig. 3 is a detail perspective View of thesocket-section, and Fig. 4 is a similar view of the ballsection of theball-anol-socket joint. Fig. 5 is a detail perspective view of a portionof the main casing-section, and Fig. 6 is a detail perspective view ofthe end casing-section.

In the accompanying drawings we have illustrated our invention inconnection with one of the drive-wheels A of an automobile, the hub abeing journaled on the sleeve B of the end casing-section B and beingXed at C to the outer squared end of the shaft C2 of the ball C byfitting a squared opening in the outer end I shown in Fig. 2 ofthedrawings.v The ball C fits within the socket E and is slotted at C2 forthe passage of the pin E', Which may be covered or jacketed from end toend bya sleeve, as best shown in Fig. 2 of the drawings, to relievefriction in the operation of the ball-and-socket joint. The socket E hasfixed to it the driveshaft E2, which may be turned by any suitablegearing with the pinion e2 or in any other suitable manner, and thisshaft E2 operates within the sleeve F of the maincasing-sectionvF.

The section F, together with the section B, incloses the ball-and-socketjoint, and these sections F and B are pivoted together on opposite sidesof the ball-and-socket joint, preferably by the construction shown andwhich includes the opposite radially-projecting arms F2 on the casing F,socketed in their outer ends to receive the pivot-pins G, which latter lare secured tov the outer ends of the arms B2 ofthe casing B. 'Theradially-projecting arms F2 of the section F are rounded incross-section, and the arms B2 of the casing B are provided in theirinner faces with rounded grooves or recesses in which fit the roundedarms F2, forming a tight joint and presentinga neat and attractiveappearance, as will be understood from Figs. l and 2 of the drawings,outer ends of the arms being Vdeflected at B3 to lap upon the outer endsof the arms F2 of the casing F, and are provided with threaded openingsZ22, in which are threaded the screws G, the said screws being extendedbeyond the threaded portion and having smooth unthreaded portions attheir inner ends turning in the sockets ,f2 on the outer ends of thearms F2 of the main casing-section. By this construction theball-and-socket joint is incased and protected from dust and moisture.

An oil-cup is formed within the main casingsection to receive the lowerportion of the .ball-and-socket joint, so the latter may run in oilplaced in the cup. This cup is preferably secured by means of a plate I,secured to the outer end of the casing-section F, as best shown in Figs.2 and 5 of the drawings.

In Fig. 2 I show the pin of the ball-andsocket joint as provided with ajacket in the form of a straight sleeve extending the full length of thepin.

As shown in Figs. l and 6, the end casingsection is provided with acrank-arm to which may be connected the rod for operation from thesteering devices for the purpose of shifting the wheel A in theoperation of steering.

Having thus described our invention, What we claim as new, and desire tosecure by Letters Patent, is

i 1. The combination of the ball-and-socket joint, the shafts projectingfrom the sections thereof, the casing-sections, the radially-projectingarmsl on one of said sections, the said arms being rounded incross-section, the radiallyprojecting arms on the other section groovedin their inner ends to receive the rounded arms of the first section,and provided at their outer ends with laterally-deflected portionslapping againstvthe ends of IOO forming1 an oil-receptacle within saidinner IO section, substantially as and for the purpose Set forth.
